WormMine: Gene WBGene00006368

• WormBase Gene ID: WBGene00006368
• Gene Name: sym-3
• Sequence Name: C54H2.1
• Brief Description: sym-3 encodes, by alternative splicing, two isoforms of a protein withno recognizably conserved domains, but with orthology to human FAM102A (EEIG1; OMIM:610891) and FAM102B, and to Drosophila CG8671; mutations in sym-3, while producing no phenotype on their own, are synthetically lethal with loss-of-function mutations in mec-8, which encodes a regulator of alternative RNA splicing; although the precise function of sym-3 is not yet known, sym-3 activity appears to be required for some aspects of pharyngeal differentiation, as mec-8; sym-3 double mutants arrest as late-stage embryos or L1 larvae with pharynges that, despite normal morphology, do not attach to the outer cuticle to allow for feeding.
• Organism: Caenorhabditis elegans
• Automated Description: Enriched in several structures, including ABalapapapa; ABalapppapa; ABplpaaappa; ABprpaaappa; and neurons based on RNA-seq and single-cell RNA-seq studies. Is affected by several genes including cyc-1; isp-1; and mrps-5 based on microarray; RNA-seq; and tiling array studies. Is affected by eight chemicals including lithium chloride; Zidovudine; and allantoin based on microarray and RNA-seq studies. Is predicted to encode a protein with the following domains: EEIG1/2-like; N-terminal C2 in EEIG1 and EHBP1 proteins; and NT-type C2 domain. Is an ortholog of human EEIG1 (estrogen-induced osteoclastogenesis regulator 1) and EEIG2 (EEIG family member 2).

Bacteria diet: Sphingomonas aquatilis Yellow. Fed for 30 generations.	Transcripts that showed significantly decreased expression after fed by bacteria Sphingomonas aquatilis (Yellow) for 30 generations comparing to animals fed by E. coli OP50.	DESeq2 fold change > 2, p-value < 0.01.	WBPaper00061007:S.aquatilis_downregulated
	Transcripts that showed significantly decreased expression in mdt-15(mg584gf) comparing to in N2 at L4 larva stage.	EdgeR, fold change > 2, FDR < 0.001.	WBPaper00056290:mdt-15(mg584)_downregulated
	Maternal class (M): genes that are called present in at least one of the three PC6 replicates.	A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing.	[cgc5767]:expression_class_M
	Transcripts that showed significantly increased expression in aak-1(tm1944);aak-2(ok524) animals comparing to in N2.	DEseq 1.18.0, adjusted p-value < 0.05.	WBPaper00056471:aak-1(tm1944);aak-2(ok524)_upregulated
	Strictly maternal class (SM): genes that are the subset of maternal genes that are not also classified as embryonic.	A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing.	[cgc5767]:expression_class_SM
	Transcripts that showed significantly increased expression in 10-days post L4 adult hermaphrodite N2 grown at 20C, comparing to in 1-day post L4 adult hermaphrodite N2 animals grown at 20C.	CuffDiff, fold change > 2.	WBPaper00065096:Day10_vs_Day1_upregulated
	Transcripts that showed significantly increased expression in xrep-4(lax137).	DESeq2. Genes were selected if their p value < 0.01.	WBPaper00066062:xrep-4(lax137)_upregulated
	Genes that showed expression levels higher than the corresponding reference sample (L2 all cell reference).	A Mann-Whitney U test with an empirical background model and FDR correction for multiple testing was used to detect expressed transcripts (Benjamini and Hochberg 1995). Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models. Genes and TARs were called differentially expressed if the FDR was <= 0.05 and the fold change (FC) >= 2.0. To more strictly correct for potential false-positives resulting from multiple sample comparisons, authors divided individual FDR estimates by the number of samplesor sample comparisons, respectively. This resulted in an adjusted FDR of 1.3 * 0.0001 for expression above background and of 7.4 * 0.0001 for differential expression. Authors called genes selectively enriched in a given tissue if they met the following requirements: (1) enriched expression in a given tissue (FDR <= 0.05 and FC >= 2.0), (2) fold change versus reference among the upper 40% of the positive FC range observed for this gene across all tissues, and (3) fold-change entropy among the lower 40% of the distribution observed for all genes.

Temprature shift to 28C for 48 hours.	Transcripts that showed significantly decreased expression after animals were exposed to 28C temperature for 48 hours.	Differentially expressed genes wereidentified using DESeq (v.1.18.0) by normalizing readsbased on the negative binomial distribution method andcomparing each HS timepoint to the 0-h control.

WBPaper00037950:all-neurons_L2-larva_expressed
	Genes that showed oscillating mRNA expression level throughout the 16 hour time courses from L3 larva to young adult.	The following three lines of R code were used to perform the classification: increasing <-2*amplitude-PC1 < -1.7; oscillating <-!increasing & (amplitude > 0.55); flat <-!increasing & !oscillating; Note that the amplitude of a sinusoidal wave corresponds to only half the fold change between trough and peak.

Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type.
